Start a large pot with cold, salted water on the stove to boil. Peel and cut the potatoes into 1-inch cubes.
Add potatoes to pot and bring to a boil, then reduce to medium low heat to simmer for 12-15 minutes, or until potatoes are soft.
Drain and place the potatoes in a large bowl. Mash well with a fork or mixer until desired consistency.
Add in the cream cheese, butter, and sour cream until well combined.
Stir in seasonings (garlic powder, smoked paprika, salt and pepper) and one cup of shredded cheddar cheese. Adjust salt and pepper to taste.
Spread potato mixture into a 9-inch by 13-inch baking dish. Top with remaining shredded cheese and crumbled bacon.
Bake at 350 degrees for 30 minutes. Garnish with chives and serve!
